EEG (Electroencephalogram)
About the test:
EEG is a test that detects abnormalities in your brain waves, or in the electrical activity of your brain. During the procedure, electrodes consisting of small metal discs with thin wires are pasted onto your scalp. The electrodes detect tiny electrical charges that result from the activity of your brain cells.
Documents required on the day of test:
1)Patients’ history reports
2)Doctor’s prescription
What you need to do:
1)Schedule your appointment in advance from the Center.
2)Responsible relative should accompany the patient.
3)Patients can eat food before the test.
Preparation:
1)Plan to arrive 15 minutes before your scheduled appointment .
2)Wash your hair the night before or the day of the test, but don’t use any conditioners, hair creams, sprays or styling gels. Hair products can make it harder for the sticky patches that hold the electrodes to adhere to your scalp.
3)Avoid anything with caffeine on the day of the test, because caffeine can affect the test results.
4)Take your usual medications unless instructed otherwise.
5)If you’re supposed to sleep during your EEG test, your doctor may ask you to sleep less or even avoid sleep entirely the night before your EEG.
Procedure :
1)You’ll be asked to lie down on your back in a reclining chair or on a bed.
2)The technician will measure your head and mark where the electrodes will be placed. These spots are then scrubbed with a special cream that helps the electrodes get a high-quality reading.
3)The technician will put a sticky gel adhesive on 16 to 25 electrodes. They will then be attached to various spots on your scalp.
4)Once the test begins, the electrodes send electrical impulse data from your brain to the recording machine. This machine converts the electrical impulses into visual patterns that can be seen on a screen. These patterns are saved to a computer.
5)The technicians may instruct you to do certain things while the test is in progress. They may ask you to lie still; close your eyes, breathe deeply, or look at stimuli (such as a flashing light or a picture).
6)After the test is complete, the technician will remove the electrodes from your scalp.
7)During the test, very little electricity is passed between the electrodes and your skin, so you’ll feel very little to no discomfort.
Report :
